Not too familiar with Hyperion IR measurement capabilities but I am aware that there have been some recent firmware changes that made some improvements. As such, recommend that you watch the Hyperion thread or perhaps contact Mr Mel for his recommendation.

Put 8 x Haiyin batteries in my shopping cart at haiyin.com, from 800mAh to 5000mAh, total came to US$203 - fine, that's competitive... then checked the postage = US$154! That's the cheapest international option.

Hobbyking's cart for the same size packs came to US$194 with postage at US$53. Postage cost is 1/3rd, both warehouses are in Hong Kong, Haiyin uses Fedex, HK uses SingPost.

Sorry Haiyin, I can't afford US$154 just for postage...

O wow, to South Africa. I'm guess I'm very lucky that they have a warehouse in the U.S.

If it reports individual cell IR when you toggle through the balance screens then it is the latest firmware and in my testing gives values for IR on good packs that are very close to the ESR meter and iCharger numbers. Mine is v 5.8.

Earlier firmware did not give accurate IR values and was pack only. Note you only see cell IR on the charger display - the EOS suite does not display it.

UPDATE: The individual cell IR shows in a popup on the software screen if you hover the mouse over the IR box.

Since 03Jan13, IATA Members such as FedEx, UPS and DHL can no longer ship more than "2 Lipo packs per box" outbound from Hong Kong ( i.e. no bulk shipping ). The extra weight & additional size of the shipment will add to cost.

HAIYIN do not mark up shipping costs and courier costs to South Africa are indeed high!

If there is a cheaper way to ship declared Lipos from Hong Kong, we are all ears!

Thank you for the response and explanation, could you ship through Sing Post?

Edit: I checked shipping for 2 x H800.3S.20, its still $72 for $17 worth of batteries, I think you should tell Fedex to take a hike.

I guess I don't have the latest version of software! I'll check into downloading it.

Hint, hint...it sounds like some other vendors are cheating and not really legally "declaring" lipos in their shipments. At least Haiyin is following the laws and being honest although it hurts their shipping costs.

Hi
Not taking sides here but I had occassion to order some parts from a USA source who had no UK stockist .
Cost of parts were very small but transport ( not postage ) was into telephone numbers .
Tried to get some explaination but got take it or leave it .
Between rock and hard place so got the parts sent to a friends USA address and he posted them out at very acceptable charges
I have noticed that purchasing from Hobby King and come to check out sometimes you get a comment that you can add a further ? grams to the order at no extra charge for postage .
Many of their products show a unit weight
I would suspect that a pricing deal is set up with various couriers based on fixed weight blocks so if your goods were only 0.5Kg they perhaps fell into the 0 to 9.99 Kg banding and charge was reflected accordinly .
Stand corrected and could well be wrong

Have done a quick Google search and didn't come up with a UK stockist .
Does anyone have a UK source who has stock and not just ordering to order.
With the comment from Haiyin regarding shipping quantity restrictions .possibly may lead to extended lead times
Shoot me down if it has been covered in earlier posts but did a quick read through and nothing specific noticed

Just an update, I eventually ordered batteries from another chinese supplier, shipping cost was $63 for $200's worth of batts. My first choice however was Haiyin, as everybody seems happy with them and their prices are good.
